Domestic researchers are working on a method for extracting electricity from glucose in human blood. It will be possible to apply the method in the work of pacemakers so that they function without interruptions. Scientists have reproduced models of parts of the circulatory system in the laboratory. A biofuel cell about five centimeters in size was placed in it. Specialists were able to extract electric current with a power of 15 to 40 microwatts. Pavel Gotovtsev, deputy head of the biotechnology and bioenergy department at the NBIKS-technology complex at the Kurchatov Institute, assures that this is sufficient to ensure the activity of the pacemaker of the modern model. In this case, the patient will not experience any discomfort or discomfort. The battery includes a system of a pair of electrodes and biocatalysts. When glucose decomposes, free electrons appear on the anode, moving in a chain to the cathode. Positively charged hydrogen atoms also travel across the membrane to the cathode. Gaining the lost electrons there, they form water, reacting with oxygen. Scientists believe that one operation is enough for the patient. After this, a pacemaker will be able to function for life, being in the human body and receiving a constant energy supply from the carrier’s blood. In the near future, the research team will begin testing the new development on animals.
